If needed, thaw the salmon portions completely and pat dry with paper towels.
Line the bottom of your air fryer basket with aluminum foil. (Leave the sides open so the air can circulate.)
In a small bowl, whisk together the olive oil, Dijon, salt, brown sugar, Italian seasoning, garlic powder, paprika, and pepper.
Brush the glaze on all sides of the salmon portions. Place the salmon onto the foil in a single layer, leaving a little space between each piece.
Cook at 350 degrees F for 8 minutes. Use a spatula to remove the salmon from the air fryer. Sprinkle with chopped parsley if desired, and serve warm with your favorite side or over a salad.
Notes
I leave the skin on the salmon portion so that it's more stable. The skin will come off super easy once the fish is cooked if you prefer to eat the salmon skin-off.
If you would like to use larger portions of salmon, you can. Just be sure to arrange them in a single layer in the air fryer basket.
Depending on the thickness of your salmon, you might need to cook it for 1-2 minutes more or less. I used 1-inch-thick portions of a salmon filet. It was very juicy after 8 minutes. If you like it more translucent, cook it for a minute less.
